Purpose Of Review: To discuss the recent insights into the relationships between viral respiratory infections and asthma inception in the context of a long-term goal of moving toward prevention strategies for childhood asthma.
Recent Findings: There is strong evidence for respiratory syncytial virus and human rhinovirus wheezing illnesses as important risk factors for asthma inception. The mechanisms underlying these relationships have been an intense area of study. Novel approaches for the prevention of virus infections and/or lessening the severity of associated illnesses are at various stages of development, and are important potential tools in efforts aimed at primary and secondary prevention of asthma.
Summary: Viral respiratory infections in early life are a major source of morbidity and are critical in the development of asthma. Mechanisms by which these infections lead to asthma inception in susceptible individuals are emerging. Further, there are promising potential interventions currently available that should be tested in clinical trials. The goal of prevention of disease inception is clearly on the horizon.

Background: Respiratory syncytial virus (RSV) infection in the first year of life has been linked with an increased risk for asthma. Some propose that RSV-induced inflammation leads to lasting airway changes, while others contend that RSV bronchiolitis is a marker for underlying predisposition. Social distancing adopted during the COVID-19 pandemic has led to a dramatic reduction in RSV activity, providing an unexpected opportunity to investigate this debate.

In the last three decades, the overall prevalence of asthma appears to be plateauing, although large geographical and socioeconomic variation is evident. Overall, asthma prevalence slightly decreased in most age groups, except for school-aged children. Of note, asthma mortality steadily decreased, potentially highlighting improved asthma management strategies.

Background: Ambient (outdoor) air pollutant exposures have emerged as a plausible risk factor for incident childhood asthma. However, the effect of ambient air pollutant exposures on risk of incident adult asthma is unclear. We aimed to investigate associations between specific ambient air pollutants and the risk of incident adult asthma.

A subset of children and adolescents experience recurrent or persistent symptoms following SARS-CoV-2 infection, known as postacute sequelae of COVID-19 (PASC), however, the clinical epidemiology within the United States (US) is not yet well understood. This scoping review aims to synthesize the clinical epidemiology of pediatric PASC in the US. A comprehensive literature search was conducted and databases were queried from inception until January 29, 2024.
